Currently i grab feeds like:

PHP Code:
$x simplexml_load_string($news_xml);
$x->channel->item as $item){
$item_date = (string) $item->pubDate;
$item_desc = (string) $item->description;

This has worked fine until i hit a feedburner feed that is different. It uses <entry> and <content type="html" xml:lang="en-US" xml:base="">. It also uses <feedburnerrigLink> for the proper link.

How can I make my php accept this new format as well as the normal method most rss feeds seem to use?
